KirklandDynamics <br /> Code Calculation Per ASME BPVC VIII Rules for the Construction of Pressure Vessels Division 1 -2013: <br /> Maximum Allowable Stress, SA249 (304 Stainless Pipe) = 20,100 psi C36.1 <br /> **The above Maximum Allowable Stress from the ASME Boiler and Pressure Vessel Code VIII Division 1 <br /> includes a Factor of Safety as well as limits for Fatigue Design. The Maximum Allowable Stress shall be <br /> used to determine either the thickness of materials used in the construction of the pressure vessels or <br /> the determination of the Design Pressure. <br /> Determine Maximum Shell Pressure of Item 18—Collection Vessel (Largest Diameter) <br /> E =Joint Efficiency(Specified in UW-12,ASME BPVC VIII Division I), Use 1 No Welds <br /> P= Internal Design Pressure, Psi <br /> R= Inside radius of shell, in <br /> S= Maximum Allowable Stress value, Psi (20,100 psi for SA-249; 304 SS) <br /> t= Minimum required thickness of shell, in <br /> for Cylindrical shells <br /> (1) Circumferential Stress: <br /> P = SxExt/(R+0.6xt) Equation 1, UG-27 <br /> P = [20,100 psi x 1 x 0.13 in] /(4.87 in—1 x 0.13 in) <br /> 551 psi C36.2 <br /> (2) Longitudinal Stress: <br /> P= 2xSxExt/(R-0.4xt) Equation 2, UG-27 <br /> [2 x 20,100 psi x 1 x 0.13 in]/(4.87 in —0.4 x 0.13 in) <br /> 1,084 psi C36.3 <br /> **Maximum Pressure for Collection Vessel Shell is 551 psi per Equation 1, UG-27. <br /> 9/1/2015 Project: 150703 Terpp MK IV CLE Report Page 36 of 44 <br /> KD Doc. 150703ER <br />
